Abstract
An apparatus for gas/solids exchange has a column having a plurality of vertically spaced grates on which the granular solids can form beds to be traversed by the gas. Each grate is provided in a grate plane by a plurality of fixed grate bars interdigitated with movable grate bars forming a planar unit which can be displaced by a controller out of the grate plane to allow the granular solids on the respective grate to trickle downwardly uniformly over the cross section of the column onto the next lower grate.
